Note 1:
When an I/O register is modified as a function of itself ( e.g.,
MOVF
PORTB, 1), the value used will be that value present
on the pins themselves. For example, if the data latch is ’1’ for a pin configured as input and is driven low by an external
device, the data will be written back with a ’0’.
2:
If this instruction is executed on the TMR0 register (and, where applicable, d = 1), the prescaler will be cleared if
assigned to the Timer0 Module.
3:
If Program Counter (PC) is modified or a conditional test is true, the instruction requires two cycles. The second cycle is
executed as a
NOP
.
Note:
Additional information on the mid-range instruction set is available in the PICmicro
